Abstract
In this paper, the problem of designing an H2 output feedback controller for a class of uncertain systems with time-varying delays is investigated. These systems are evolve in the continuous-time space against a wide class of parametric uncertainties which belong to a convex bounded polytopic domain. The objective is to derive tractable synthesis conditions for the robust feedback design. Two design methods are established: the first uses bounds on the delay pattern and the second utilizes instantaneous delay measurements. All the developed results are cast in the format of linear matrix inequalities (LMIs) and numerical examples are presented.
